This module aims to help the student to understand the Energy in its various forms and to relate the Physics concepts with life, the environment and the daily life of the individual and the community. The issue of renewable energy is also discussed.

Message: There is no life without Energy.

Energy and Plants:Divided into five different activities (1 to 5) that aim to demonstrate that plants are fundamental agents in the process of converting sunlight energy in a format that can be used by other organisms, sustaining a process of energy transfer on Earth.

1) Leaf collection and classificationLeaf collection activity in the community environment, aiming to perceive the diversity of leaves of plants in a natural environment and the different criteria that can be used for its classification (this subject is also studiedin the DNA Module, Diversity and Heredity).

2) What bubbles are these? Experiment that involves the production of oxygen during the conversion of energy made by plants (photosynthesis). The observation is made through bubbles formed in the water containing aquatic plants exposed to the sun.

3) The fluorescence of a solution: To demonstrate, through a simple experiment that uses the alcohol extract of the collected leaves, the reaction that occurs when the chlorophyll comes in contact with the light.

4) The mysterious hidden colors of green plants: To separate the different colors that emerge from a green plant, To observe the different pigments that can be separated by the method of chromatography on paper (this procedure is also studied in the module DNA, Diversity and Heredity).

5) The production of starch in plants: An activity that aims to compare what occurs in leaves that are prevented from photosynthesis because they are covered with aluminum foil against leaves that do photosynthesis. The objective is to understand which are substances that storage the energy produced in the process of photosynthesis.

6) The origin of the winds: Practical activity with balloons and glass jars that aims to explain how the winds arise from the displacement of air masses with different temperatures.

7) Light from a blow: To understand through the construction of a Savonius Wind Rotor, the transformation of wind energy into electricity and its importance as a source of renewable energy.

8) Water Cycle: To approach through a simple experiment the water cycle and through it to make the participants understand how this process happens in nature, also relating it to environmental education themes.

9) Hydroelectric: To conduct participants to build a “mini hydroelectric plant” that generates enough electric energy to light an LED lamp. Discuss the importance of water and how it can be used as an energy source.

10) Solar – thermal: Through several practical activities, such as exposing different materials to the sun and heating water in plastic bottles, to demonstrate how sunlight can generate thermal energy and discuss relevant issues such as the greenhouse effect and its consequences.

11) Photovoltaic: To present several modern tools and instruments that use sunlight to generate electricity. The goal is to explain how these devices work and how they can produce energy that can be used in households and communities.

12) Systematizing and integrating knowledge:The contents covered in all activities are discussed and analyzed daily with the use of an interactive panel, where the various elements are inserted and modified by the participants themselves, aiming to integrate the knowledge acquired.
